基于朗肯循环液化天然气冷能利用

Cold Energy Utilization of Liquefied Natural Gas Based on Rankine Cycle

当前LNG接收站正处在蓬勃发展阶段。LNG接收站在LNG气化的过程中会释放出大量的冷能,LNG气化过程冷能的回收利用是提高接收站能量利用率和节能降耗的重要手段。通过对基于朗肯循环的LNG冷能回收过程进行分析研究,分别对循环过程中单一循环工质和不同配比的混合循环工质性能表现进行了对比研究。

At present,LNG terminals are in a stage of vigorous development.LNG terminal will release a lot of cold energy in the process of LNG gasification.The recycling of cold energy in LNG gasification process is an important means to improve the energy utilization rate of the terminal and save energy and reduce consumption.In this paper,through the analysis and research of LNG cold energy recovery process based on Rankine cycle,the performance of single working medium and mixed working medium with different proportions in the cycle process were studied and compared.
